Tensile stress changes indicate clear contribution of compaction to the total index change.Fiber Bragg gratingsPhotosensitivityBi-doped fibersFabrication/Characterization of Fiber Gratings and Photosensitivity in Ge-Free Bi-Al-Silica Fiberstext::conference output::conference proceedings::conference paper
